2,2MW - I>1.2In, 10s, I>>2.5In; Un=75%, 5s
4.375MW, I>1.2In, 5s, I>>1.5In, 0.5s. Un=75, 5s.
Why Connect the transformer to the generator before starting the generator if possible could be ok or not, please interpret more.
The trip is due to low voltage. we believe it is due to over current, but why it is trip of low voltage.
can we block current protection for this case, I think differical protection is main one, after we finish start up , we can setting over current.
11Kv SYSTEM with only generator as power source, 2x2.2MW+3x4.375, the short circuit proctection setting for 2,2MW - I>1.2In, 10s, I>>2.5In; 4.375MW, I>1.2In, 5s, I>>1.5In, 0.5s.
We put one 10MVA transformer in, all of Genset shunt down due to inrush current of closing.
My question is how to...
If it is 400V GENSET to 400V motor, it is OK. But it is 3.6KV ESP pump, 400V genset - step up transformer 3.6KV - ESP pumps, the MV pumps starting shall be considered in this case.
I have a ESP pumps skid, the configuration is 400VAC incoming - VFD - step up transformer 0.4/3.6KV - ESP pumps (280kW), this skid is powered by 400vac genset, my question is the minimum capacity of genset?
One turbine motor 5.5WM, 11kV, short circuit 25KA, NGR 100A, 63.5ohms, 10s. How to select the cable to the NGR, I believe its size is half of the cable phase to phase 1x240sqmm, it is OK, it seems too big. It is right to choose cable just meet 100A.
An Iran project located in swamp, power for OGM (oil gatherthing manifold) 100kW, if 11KV OHL to swamp, cost is very high due to foundation design, constrcution is not easy.
I heard there is kind of special generator with assocated gas as driven power(not normal gas engine, here, gas is as...
